I have been programming on computers since the ZX81.
I am an apprentice trained Electronics Engineer with qualifications to back it up.
I have been repairing computers since 1996.
Yet to some people I still know nothing...

ja, that's great. it can, and is done. but i'll add that NO spdif audio connection needs to be made in the setup my brother has. but he IS using the same adapter(dvi->hdmi) shown in the how-to, except that it is single-link on the dvi side.

unfortunately, the article does not get into HOW the technology works.

getting back to this... maybe someone will know what kind of multiplexing is done to get both audio and video trasfered over this dvi adapter.been reading up a little and the Wikipedia page list 6 kinds possible....spacefrequencytimepolarizationorbital angular momentumcodehttps://en.wikipedia.org/wiki/Multiplexing

I've learned that Serial Attached Scsi (SAS) transmission maintains more than one data stream per channel on a single cable (4 stream per cable, but supports ALOT of drives)using time-division multiplexing, or at least that's what I've read. is this the same way the dvi adapter is getting it done?

DVI audio is non-standard. What they most likely do is place a digital audio signal on pins reserved for analog. So you must have a card that supports it as well as an adapter that came with the card, or else it won't work.

Have done a lot of browsing on the subject, nothing definitive except that the video card must have a multiplexing chip in its design for carrying audio on the video stream.

for me it is normal, the drivers for my nvidia GT240 comes with high definitions audio drivers that I think are intended for carries sound trough the video cable. I even see VGA-RCA adaptors that came with an output audio cable
